| Brief Description: The tornado that went across southeast Adams County entered Brown County about 750 pm CDT southwest of Highway 24 and Timewell. Witnesses observed a multiple vortex tornado that damaged one home, two out-buildings, several machine sheds, and several grain bins. Approximately three miles northeast of Timewell the tornado damaged another farmstead and numerous trees. Six machine sheds were destroyed while a home sustained damage to the roof and the west and south walls. A number of large trees in the vicinity of the farmstead were also damaged. Five miles northwest of Mount Sterling, several witnesses observed a multiple vortex pattern with several smaller tornadoes rotating around a larger tornado. The width of the damage area (mainly trees) varied from 50 to as large as 300 yards. Numerous trees were snapped at the base of the tree and tossed northeastward. The damage intensity was estimated from F1 to the lower end of F2. The tornado continued to travel northeast crossing county road 1500 north (5 miles north-northwest of Mount Sterling). Several large trees were either snapped half-way or uprooted at this location. Damage path width ranged from 50 to as large as 100 yards while damage intensity was estimated at the lower end of F1. The tornado damage intensified a second time as the tornado moved across Illinois Highway 99, 7 miles north of Mount Sterling. One old farm home and a large barn were completely destroyed with debris tossed 1/3 mile to the east. A second farmstead 1/2 mile east experienced damage to several machine sheds, grain bins and a barn. The nearby home sustained little damage. Several large trees in the vicinity of the barn and machine sheds were uprooted or snapped near the base of the trunk. The width of the damage pattern over this area varied from 50 to 100 yards. Damage intensity ranged from F1 to lower end of F2. Many witnesses along the track of this tornado did not hear the classic "freight train" sound as heard in other cases. Rather they heard a "swishing" type sound. Additionally, many witnesses did not observe lightning or hear thunder as the tornado passed.

| Brief Description: After dissipating just west of Atlanta, a new tornado touched down 1 mile southeast of Atlanta and moved northeast into Knox County. In Macon County, 5 single family residences and 3 mobile homes were destroyed from 2 miles east of Atlanta to 10 miles northeast of Atlanta. Four single family homes were damaged within this area. Several outbuildings were also damaged or destroyed. Some damage south of the tornado track was likely due to the very intense rear flank downdraft, which storm spotters observed to accompany the storm. Severe weather broke out in northwest and west-central Missouri around midday on April 8. Storms tracked rapidly northeastward and moved into central and north-central Missouri by early evening. The outbreak included at least five tornadoes, one of which moved along a 54-mile path across three counties. Reports of thunderstorm wind damage were also widespread throughout the area. | |||||||||||
